This has been discussed and answered over A suggested workaround is to disable RTX HDR specifically for sunshine.exe and available to leave the option enabled globally if you want. Side note = HDR must be enabled in Windows settings to configure this option inside the Nvidia app. |

I also noticed that RTX-HDR is not properly streamed with sunshine/moonlight, despite clearly active on the host-system. It doesn't have anything to do with the issue that sunshine is not working when RTX HDR is enabled globally. Even when RTX-HDR is only enabled for a specific game, the hdr-signal somehow get's lost in the stream. |

I can confirm that streaming of RTX-HDR is still an issue after the restart-fix. AutoHDR works without problems, but RTX-HDR somehow doesn't work. Hope this can be fixed soon. |

We don't really control what Windows does or does not capture. Some things like Auto HDR do get captured by the DXGI Desktop Duplication API, while others happen deeper in the driver or display pipeline (AFMF, RTX HDR) which don't get captured. We can see if Windows.Graphics.Capture API from #2149 can capture it, but if not, there's nothing really we can do to solve this. It would be a feature request to Nvidia to support display capture of RTX HDR effects (which may be a substantial engineering effort for them). |

@cgutman Thank you for this helpful explanation. Then let's hope that the mentioned Windows-API can capture RTX-HDR. If not at least AutoHDR can be used as a fallback in some games. |

After building and trying out #2149, it doesn't seem to capture RTX-HDR in its current iteration. |

That's a shame. So i guess we have to wait for another solution. But thanks anyway for testing. |

Not fixed. This is not the problem being discussed here. See above why. |

Has anyone tried the new mod that enables fake HDR upscaling of SDR using Nvidia's new RTX HDR feature? Its called NvTrueHDR over on NexusMods. It works a treat locally and as Digital Foundry has said (go check their article on Eurogamer) it beats Microsoft's Auto HDR.
Any ideas why this wont work when using Moonlight game streaming? Moonlight gamestream can do HDR streaming no problem using its Sunshine backend. Windows 11 Auto HDR or native HDR works and games look great on the client.
When I tried this mod, the streamed version was not HDR and the HUD option was not showing the squares on the streamed end even though its clearly in HDR on the client PC's HDR monitor at the same time with the little squares present too.
EDIT:
So looks like this RTX HDR is becoming a supported feature of the new Nvidia App. I wonder if it still wont work over a Moonlight stream when they release it officially. If it does not change much technically, I expect it still wont work on a streamed game. What a shame.
